Chapter 4 Creating and Administering Clusters 57
Use Network Interface
Restrict distributed processing activity to a particular network interface card by
choosing it from this pop-up menu. If you do this on a service node computer, use
a different computer to submit Compressor jobs and batches.
Enable Port Range
With Apple Qmaster 3, you can define which ports Apple Qmaster uses for service
advertisements with the Enable Port Range checkbox and text fields in the Network
section of the Apple Qmaster pane in System Preferences.
To define ports for Apple Qmaster service advertisements:
1 Open the Apple Qmaster pane in System Preferences.
2 Click Advanced to open the Advanced pane.
3 Select Enable Port Range.
4 In the From field, enter any integer value between 50,000 and 65,535 to set the start
of the range, such as 50,000.
5 In the “Number of ports” field, enter the size of the range, such as 1,000.
Extras
Use these features to configure additional settings.
Log service activity to file
If selected, an activity log is created and updated regularly with information about the
Apple Qmaster actions on this computer. Logs are stored in /Library/Logs/Qmaster/.
To turn this feature off, deselect the checkbox.
Note: You can also access this log information using the Log button in
Apple Qadministrator or the Log tab in Batch Monitor.
Show Qmaster service status in menu bar
If selected, an Apple Qmaster icon appears in the computer’s menu bar. The menu bar
item provides Apple Qmaster status and activity information. For more information, see
“Service Node Status Indicator in the Menu Bar” on page 44.
Identify this computer to Apple Qadministrator as
By default, a computer is identified on the network by its computer name (as it is
entered in the Sharing pane in System Preferences). You can change this name to
something more meaningful if you like, since it is the name used to identify this
computer in the Apple Qadministrator application. If you are setting up a managed
cluster controller, this is the name that will appear in the Apple Qadministrator
Controller pop-up menu.
